[0061] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0062] The conveyor line, also known as the assembly line, is mainly used to transport materials. It is usually composed of a combination of different types of conveyors to form a continuous assembly line that can automatically transport items. At present, the conveyor line adopts a centralized cache loading method, that is, the workpieces only need to be manually placed in the conveyor line at the entrance of the conveyor line, which helps to improve the utilization rate of personnel.

[0063] As mentioned in the background technology, the conveyor line in the related technology uses a motor as a power source, and needs to cooperate with the production of a specific pallet, the workpiece is placed on the pallet, the motor drives the pallet to move, and then drives the workpiece to move in the conveyor line, which has a high cost. And the production of pallets that can hold workpieces for different workpieces further increases the production cost.

[0064] Based on the above technical problems, an embodiment of the present application provides a conveyor line, in which the technical solution includes a mounting bracket, a stop mechanism and a lifting assembly; the mounting bracket is provided with a slideway, and the slideway is inclined, and the slideway is used to support at least two workpieces so that the workpieces slide under their own gravity. The stop mechanism is configured so that part of the stop mechanism extends into the slideway to release at least one workpiece located in the front and block at least one workpiece behind; the lifting assembly is used to lift the workpiece that slides along the slideway to a preset position. In this way, the workpiece is moved by sliding the workpiece in the inclined slideway using its own gravity, and the workpiece is blocked by the stop mechanism, so that the workpiece can be cached, and finally the workpiece is lifted by the lifting assembly. In the above process, there is no need to use a motor as a power source for moving the workpiece, and there is no need to make a pallet, which has the effect of reducing the production cost.

[0065] It should be noted that Figures 1 to 14 The schematic diagram of each component in the conveyor line is shown. The specific structure of the remaining components in the conveyor line is not limited to Figures 1 to 14 of examples.

[0066] The present application is described in detail below with reference to the accompanying drawings and specific embodiments:

[0067] Reference Figure 1 , Figure 2 and Figure 3 As shown, a conveyor line provided in an embodiment of the present application includes a mounting bracket 100, a stop mechanism 200 and a lifting assembly 300;

[0068] The top of the mounting bracket 100 is provided with a slideway 101 , which is used to support at least two workpieces. The slideway 101 is inclined relative to the ground so that the workpieces can slide in the slideway 101 due to their own gravity.

[0069] The stopping mechanism 200 is disposed on the mounting bracket 100 , and the stopping mechanism 200 is configured such that a portion of the stopping mechanism 200 extends into the slideway 101 to release at least one workpiece located in the front and block at least one workpiece behind.

[0070] The lifting assembly 300 is disposed on the mounting bracket 100 , and the lifting assembly 300 is used to lift the workpiece that slides along the slideway 101 to a preset position to a gripping position of the robot arm.

[0071] In the above embodiment, the operator first places the workpieces in the slide 101 in sequence. Due to the inclined setting of the slide 101 and the gravity of the workpieces themselves, the workpieces slide along the inclined extension direction of the slide 101. When the workpiece slides to the position of the lifting assembly 300, the lifting assembly 300 lifts the workpiece to the gripping position of the robot arm. This process does not require the use of a motor as a power source to drive the workpiece to move, nor does it require the manufacture of a specific tray for holding the workpiece, which has the effect of reducing production costs.

[0072] In a possible implementation, fences 400 are provided on both sides of the mounting bracket 100 in the length direction, and the fences 400 and the mounting bracket 100 are jointly arranged to form a slideway 101. The fences 400 and the mounting bracket 100 are jointly arranged to form the slideway 101, which is equivalent to having a limiting effect on the movement of the workpiece, preventing the workpiece from falling off the slideway 101, and helping to improve the movement stability of the workpiece.

[0073] Reference Figure 3 and Figure 8 As shown, specifically, the stop mechanism 200 includes a first stop assembly 210 and a second stop assembly 220. The first stop assemblies 210 are disposed on both sides of the slideway 101 and are symmetrically arranged in groups of two.

[0074] The first stopping assembly 210 includes a first supporting plate 211 , a second supporting plate 212 , a first stopping member 213 and a first stopping cylinder 214 .

[0075] The first support plate 211 is connected to the mounting bracket 100, the second support plate 212 is connected to the side of the first support plate 211 away from the mounting bracket 100, the first stop member 213 is used to be hinged to the second support plate 212 through a bearing seat, the first stop cylinder 214 is arranged on the first support plate 211, the piston rod of the first stop cylinder 214 is connected to one end of the first stop member 213, the first stop cylinder 214 is extended and retracted to control the rotation of the first stop member 213, so that part of the first stop member 213 withdraws or extends out of the slide 101.

[0076] In the above embodiment, when the first stop cylinder 214 contracts, it drives the first stop member 213 to rotate so that part of the first stop member 213 extends out of the slide 101. At this time, the first stop member 213 abuts against one of the workpieces to prevent the workpiece from continuing to slide, and the other workpieces abutting against the workpiece stop sliding at the same time, which is equivalent to completing the caching of the workpieces, so that one or more workpieces are cached in the slide 101.

[0077] When the first stop cylinder 214 is extended, part of the first stop member 213 is withdrawn from the slideway 101, and the workpiece in the slideway 101 can continue to slide due to its own gravity. By controlling the extension and retraction of the first stop cylinder 214, the movement of the workpiece in the slideway 101 is controlled, and the workpiece is cached in the slideway 101, which has the effect of simple control and simple operation.

[0078] Reference Figure 1 , Figure 4 and Fig. 9 As shown, in order to prevent the workpiece from sliding out of the slide 101, at least one first stop assembly 210 is provided at the end of the slide 101 close to the ground. At this time, the first support plate 211 is connected to the mounting bracket 100, and the second support plate 212 is connected to the side of the first support plate 211 away from the mounting bracket 100. The first stop member 213 is used to be hinged to the second support plate 212 through a bearing seat. The first stop cylinder 214 is arranged on the second support plate 212, and the piston rod of the first stop cylinder 214 is connected to one end of the first stop member 213. The first stop cylinder 214 is retracted to control the rotation of the first stop member 213 so that part of the first stop member 213 withdraws or extends out of the slide 101.

[0079] It should be noted that the first support plate 211 and the second support plate 212 only serve to connect the mounting bracket 100 and the first stop cylinder 214, and the first stop member 213 is hinged to the second support plate 212. The specific structure of the first support plate 211 and the second support plate 212 can be changed according to the needs of the connection position, and the specific shapes of the first support plate 211 and the second support plate 212 are not limited here.

[0080] Reference Figure 1 , Figure 3 and Fig.10 As shown, in a specific implementation, when the first stop assembly 210 blocks the sliding of multiple workpieces, that is, multiple workpieces are cached in the slide 101, at this time, only the next workpiece needs to slide to the lifting assembly 300, that is, the first stop assembly 210 needs to release only one workpiece to continue sliding. At this time, the stop mechanism 200 also includes a second stop assembly 220. Specifically, the second stop assemblies 220 are arranged on both sides of the slide 101, and are symmetrically arranged in groups of two.

[0081] The second stopping assembly 220 includes a third supporting plate 221 , a fourth supporting plate 222 , a second stopping cylinder 223 and a second stopping member 224 .

[0082] The third support plate 221 is arranged on the mounting bracket 100, the second stop cylinder 223 is arranged on the side of the third support plate 221 away from the mounting bracket 100, the piston rod of the second stop cylinder 223 is connected to the fourth support plate 222, the second stop member 224 is connected to the fourth support plate 222, and the second stop cylinder 223 is configured to drive the fourth support plate 222 to move so that the second stop member 224 is inserted into the workpiece or abuts against the workpiece to stop the workpiece from sliding.

[0083] Specifically, the first stopper 213 is a stopper plate, and the second stopper 224 is a stopper needle.

[0084] In the above embodiment, the extension and retraction of the second stopper cylinder 223 drives the second stopper 224 to be inserted into the workpiece or to abut against the workpiece to stop the workpiece from sliding. It should be noted that the second stopper assembly 220 is arranged on one side of the first stopper assembly 210. When the first stopper assembly 210 abuts against a workpiece and blocks the workpiece from sliding further, the second stopper cylinder 223 drives the second stopper 224 to be inserted into another workpiece or to abut against another workpiece. It can block the sliding of the workpiece. It can be understood that at this time, at least two workpieces are respectively restricted from sliding by the first stopper assembly 210 and the second stopper assembly 220. At this time, after the first stopper assembly 210 releases one of the workpieces, the workpiece blocked by the second stopper assembly 220 cannot continue to slide, which is equivalent to the first stopper assembly 210 only releasing one workpiece to slide. The number of workpieces loaded can be controlled, the operation process is relatively simple, and it is more convenient for the operator to inspect.

[0085] It should also be noted that the number of the stop mechanisms 200 can be selected as needed, that is, the number of the first stop assembly 210 and the second stop assembly 220 can be selected according to the working conditions. When the stop mechanism 200 is set to one, it is equivalent to having one position for caching workpieces. When the stop mechanism 200 is set to multiple, it is equivalent to having multiple positions for caching workpieces, thereby realizing the caching of multiple groups of workpieces. There is no need for the operator to perform loading operations continuously for a long time, which can reduce the labor intensity of the operator.

[0086] In one possible implementation, refer to Figure 1 , Figure 3 and Fig.11 As shown, in order to prevent the workpiece from sliding too fast and causing impact damage to other parts, the conveyor line also includes a deceleration assembly 500, the deceleration assembly 500 includes a deceleration member 510, and the deceleration member 510 includes a deceleration bracket and a deceleration roller 513 rotatably connected to the deceleration bracket.

[0087] The reduction bracket includes a fifth support plate 511 and two sixth support plates 512 .

[0088] The fifth support plate 511 is connected to the mounting bracket 100 , the two sixth support plates 512 are symmetrically arranged on the fifth support plate 511 , the reduction roller 513 is rotatably connected between the two fifth support plates 511 , and part of the reduction roller 513 is located in the slideway 101 and is used to abut against the workpiece.

[0089] In the above embodiment, when the workpiece slides in the slide 101 due to gravity, the speed of the workpiece will continue to increase due to the existence of gravity acceleration, which is not conducive to the control of the workpiece. A deceleration assembly 500 is added to the slide 101. During the sliding process, the workpiece abuts against the deceleration roller 513 of the deceleration assembly 500, and the deceleration roller 513 rotates. The deceleration roller 513 can use the damping effect to decelerate the workpiece to prevent the workpiece from sliding too fast.

[0090] In a specific implementation, the outer circumference of the speed reduction roller 513 is wrapped with a rubber sleeve, which can increase the friction between the workpiece and the speed reduction roller 513 and further improve the speed reduction effect.

[0091] Specifically, deceleration members 510 are provided on both sides of the slideway 101 in the length direction, and are symmetrically arranged in groups of two, which helps to evenly apply force to the workpiece, decelerate the workpiece more quickly, and prevent the workpiece from tilting relative to the slideway 101.

[0092] In addition, the number of the deceleration rollers 513 is set to at least two, which helps to further improve the deceleration effect.

[0093] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the conveyor line further comprises at least one roller guide 600 .

[0094] The roller guide rails 600 are arranged in the slideway 101 at intervals along the length direction of the slideway 101 .

[0095] In the above embodiment, the roller guide rail 600 can make the workpiece slide more smoothly and increase the loading speed of the workpiece.

[0096] Reference Figure 2 , Fig.12 , Fig.13 and Fig.14 As shown, the lifting assembly 300 includes a seventh support plate 310 , a lifting cylinder 320 , a lifting bracket 330 and at least one lifting claw 340 .

[0097] The seventh support plate 310 is connected to the mounting bracket 100 , the lifting cylinder 320 is connected to the seventh support plate 310 , and the piston rod of the lifting cylinder 320 is connected to the lifting bracket 330 to drive the lifting bracket 330 to rise and fall.

[0098] The lifting claws 340 are symmetrically connected to the lifting bracket 330 in groups of two, and the two lifting claws 340 in a group are used to lift a workpiece that slides to a preset position.

[0099] In the above embodiment, the lifting cylinder 320 drives the lifting bracket 330 to move, and the lifting bracket 330 drives the two lifting claws 340 in a group to move, and the two lifting claws 340 lift a workpiece to the grasping position of the robot arm.

[0100] Specifically, the connection line of the two lifting claws 340 in pairs is perpendicular to the extension line of the slideway 101. The lifting claws 340 can pass through the bottom of the slideway 101 and abut against the workpiece, thereby lifting the workpiece. The lifting assembly 300 has a simple structure and a simple lifting process, which helps to reduce manufacturing costs.

[0101] In a specific implementation, a plurality of lifting claws 340 may be provided on the lifting bracket 330. Fig.12 As shown, two groups of lifting claws 340 are provided on the lifting bracket 330. The lifting cylinder 320 can be extended and retracted at one time, so that two workpieces can be lifted at one time by the lifting bracket 330. Moreover, the height of the two groups of lifting claws 340 from the lifting bracket 330 can be adjusted as needed to adapt to different robotic arms for grasping, which has the effect of not interfering with different robotic arms grasping different workpieces and can improve the grasping efficiency of the robotic arms.

[0102] Here, the lifting assembly 300 also includes at least one guide piston 350, which is connected to the seventh support plate 310, and the piston rod of the guide piston 350 is connected to the lifting bracket 330. During the movement of the lifting bracket 330, the guide piston 350 can play a guiding and limiting role to improve the stability of the movement of the lifting bracket.

[0103] Continue to refer to Fig.12 , Fig.13 and Fig.14 As shown, the lifting claw 340 includes a connecting plate 341 , a detection member 342 , at least three first guide plates 343 and at least one positioning column 344 .

[0104] The connecting plate 341 is connected to the lifting bracket 330, at least three first guide plates 343 are connected to the top surface of the connecting plate 341, and the positioning column 344 is arranged on the side of the connecting plate 341 facing the lifted workpiece, so that the lifted workpiece can abut against the connecting plate 341 under the guidance of the first guide plate 343, and at the same time, the positioning column 344 can be inserted into the positioning hole on the workpiece.

[0105] Specifically, the three first guide plates 343 are respectively disposed at three sides of the connecting plate 341 , and are all inclined toward the connecting plate 341 .

[0106] The detection member 342 is configured to be disposed on the connection plate 341 , and after detecting that the connection plate 341 is in contact with the lifted workpiece, the robot arm is controlled to grab the lifted workpiece.

[0107] In the above embodiment, the lifting cylinder 320 drives the lifting bracket 330 to move toward the lifted workpiece, and the lifting claw 340 on the lifting bracket 330 first abuts against the lifted workpiece. At this time, the detection part 342 controls the stop mechanism 200 to prevent the sliding of other workpieces. Under the action of the first guide plate 343, the lifted workpiece abuts against the connecting plate 341. At the same time, the positioning column 344 is inserted into the positioning hole on the workpiece, and the lifting claw 340 continues to move to lift the lifted workpiece to the grabbing position of the robotic arm.

[0108] It should be noted that the lifting bracket 330 can be configured as needed, and the specific structure of the lifting bracket 330 is not limited here.

[0109] In one possible implementation, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the conveyor line further includes an upper piece guide assembly 700 .

[0110] The upper member guide assembly 700 is connected to the mounting bracket 100, and the upper member guide assembly 700 is disposed at the top of the slide 101.

[0111] The upper piece guide assembly 700 includes at least two second guide plates 710 , which are symmetrically arranged on both sides of the slide 101 , and the two second guide plates 710 are inclined so that the two second guide plates 710 are open as a whole to guide the workpiece into the slide 101 .

[0112] Here, the operator moves the workpiece to the upper piece guide assembly 700, and then places the workpiece in the slide 101 through two open second guide plates 710. The second guide plates 710 have a limiting and guiding function for the workpiece, which can place the workpiece more accurately in the slide 101, thereby improving the loading accuracy of the workpiece.

[0113] In addition, the upper piece guide assembly 700 also includes a vehicle type sensor 720, which is used to detect whether the workpiece matches the preset workpiece. When it does not match the preset workpiece, the conveyor line stops working and reminds the operator to replace the workpiece to prevent the operator from mistakenly placing a non-preset workpiece on the conveyor line.

[0114] In one possible implementation, refer to Figure 2 , Figure 5 and Figure 7As shown, the mounting bracket 100 includes a bracket body 110 and a bracket base 120 .

[0115] The stop mechanism 200 and the lifting assembly 300 are both connected to the support body 110 , and the support body 110 has a slideway 101 .

[0116] At least two mounting holes 121 are provided in the height direction of the bracket base 120 , and the bracket body 110 is bolted to the bracket base 120 through one of the mounting holes 121 .

[0117] In the above embodiment, the bracket body 110 can be bolted to the bracket base 120 through one of the mounting holes 121. It can be understood that the operator can control the bracket body 110 to be connected to the mounting holes 121 at different heights and the bracket base 120, thereby controlling the inclination angle of the bracket body 110, and then changing the inclination angle of the slide 101, thereby speeding up or slowing down the sliding speed of the workpiece, which is convenient for the operator to control the sliding speed of the workpiece.

[0118] The implementation principle of a conveyor line in the embodiment of the present application is as follows: the conveyor line includes a mounting bracket 100, a stop mechanism 200 and a lifting assembly 300; the mounting bracket 100 has a slideway 101, and the slideway 101 is inclined, and the slideway 101 is used to support at least two workpieces so that the workpieces slide in the slideway 101 due to their own gravity. The stop mechanism 200 is configured so that part of the stop mechanism 200 extends into the slideway 101 to release at least one workpiece located in the front and block at least one workpiece behind; the lifting assembly 300 is used to lift the workpiece to the gripping position of the robot arm. In this way, the workpiece is made to slide in the inclined slideway 101 by utilizing its own gravity to achieve the movement of the workpiece, and the stop mechanism 200 is used to block the sliding of the workpiece, so that the workpiece can be cached, and finally the lifting assembly 300 is used to lift the workpiece to the gripping position of the robot arm to complete the loading process of the robot arm. In the above process, there is no need to use a motor as a power source for the movement of the workpiece, and there is no need to make a tray, which has the effect of reducing the production cost.
